With the StarLC10 matrix repstrap ending up as pizza plotter, a start has been made building a new 3D machine using only the parts of 3 HP deskjet 840c printers. The printers contain many useful parts, the casing is made almost entirely out of ABS (printing material, hurray!) Especially the sliders come in nice, rectangularRead more

This makes an excellent CD-pre-listening device for our CD-sales stand at concerts. The system is fully documented (including schematics, software, PCB layout) on the wiki. Although numerous designs have beenRead more
